| Abstract: | With the development of society and the progress of science and technology, filling mining method has gradually become the main mining method on metal deposits in underground mining. There are several kinds of filling methods such as hydraulic filling, high density filling, paste filling and so on. Motion state and rheological characteristics of filling slurry in filling pipeline transportation are analyzed, and several calculation formulas of critical velocity about slurry pipeline transport are introduced. |
